I rode up zig zag lane on Boxhill today and managed to scalp a couple roadies on my mtb.
After I passed them with a cheery 'alright', I heard one say to the other 'oh the shame!'.
Later as I got to the final hairpin I thought I had them well dropped, but the first roadie wasn't taking it lying down and blew past me! Instantly I latched onto his wheel and banged up the sram gears, he knew I was there.
I knew the top wasn't far so I pulled alongside, said "race to the top?" to which he laughed, engaged the big ring and gave it full power all the way to the top, leaving him standing.
It's a bit childish but what the hell
(I ride that climb at least twice a week on my road bike so know it quite well)
